Giải thích các bước giải: `40/1000×2/1+(25+1/26)-0,008` `=0,04×2+25+1/26-0,008` `=0,08+25+1/26-0,008` `=25,072+1/26` `=651872/26000+1000/26000` `=652872/26000` `=81609/3250` `≈25,1` Học tốt!!! Trả lời
`40/1000 × 2/1 + (25 + 1/26) – 0,008` = 1/25 × 2 + 651/26 – 1/125 `= 2/25 + 651/26 – 1/125` `= 16327/650 – 1/25` `= 16301/650` Vậy `40/1000 × 2/1 + (25 + 1/26) – 0,008 = 16301/650` Trả lời

`40/1000 × 2/1 + (25 + 1/26) – 0,008`
= 1/25 × 2 + 651/26 – 1/125
`= 2/25 + 651/26 – 1/125`
`= 16327/650 – 1/25`
`= 16301/650`
Vậy `40/1000 × 2/1 + (25 + 1/26) – 0,008 = 16301/650`
